Frequency domain laser ultrasound for inertial confinement fusion target wall thickness measurements
Martin Ryzy, Guqi Yan, Clemens Grünsteidl +4
In inertial confinement fusion experiments hollow, spherical mm-sized capsules are used as a container for nuclear fuel. To achieve maximum implosion efficiency, a perfect capsule…
Frequency domain laser ultrasound microscopy for nanometric layer thickness imaging with GHz elastic plate resonances
Martin Ryzy, Guqi Yan, István Veres +6
Nanometric layer thickness imaging is crucial for fundamental research and characterization of micro fabricated devices. Here, we assess the potential of a non-contact opto-acousti…
Single-shot capable surface acoustic wave dispersion measurement of a layered plate
Georg Watzl, Stefan Eder, Martin Ryzy +4
Established techniques for characterizing a layer on a substrate system via surface acoustic wave (SAW) dispersion measurement are often slow due to the need for scanning excitatio…
Electroelastic guided wave dispersion in piezoelectric plates: spectral methods and laser-ultrasound experiments
Daniel A. Kiefer, Georg Watzl, Katharina Burgholzer +2
Electroelastic waves in piezoelectric media are widely used in sensing and filtering applications. Despite extensive research, computing the guided wave dispersion remains challeng…
